About B + W

This B+W Interference Filter has a completely colorless glass carrier coated with a number of extremely thin, partially reflecting layers with precisely computed thicknesses, similar to MC coating.

The B+W Filter 486 does not block by means of absorption, but by interference of the unwanted UV- and IR radiation that is repeatedly reflected between these layers.

It is especially recommended for CCD applications where digital image sensors have not been fitted with an IR protection filter. This filter is completely clear and it requires no increase in exposure. Its filter factor is 1.

Reviews about this item

As most, if not all, Leica M8 owners are aware incandescent lighting causes coloration difficulties unless a UV/IR lens filter is used. I purchased this filter for use during my 50th high school class reunion, which performed flawlessly over the broad spectrum of lighting situations presented. Highly recommended!!

This filter does exactly what it is designed to do. My Hutech Canon T1i is custom modified with it's infrared cut filter removed and replaced with a clear filter. This allows all spectrums to be recorded and is important for astronomical applications. However, if you want to use the camera to take regular pictures, you need this filter, but it will not prevent you from having to do a custom white balance, since the images will still come out pink. Just take a piece of white print paper and do a custom white balance under strong daylight with the filter in place. The custom white balance will remove the pink coloration, giving you the color the camera was intended to output.
